Detailed Description
Please refer to fig. 1 to 3. Fig. 1 is a schematic perspective view of a floating screw according to a first embodiment of the present utility model. Fig. 2 is an exploded view of the floating screw of fig. 1. Fig. 3 is a schematic top view of the barrel portion of the floating screw of fig. 1.
The floating screw 10 of the present embodiment includes a sleeve 11 and a screw 12. Please refer to fig. 4. Fig. 4 is a schematic cross-sectional view of the floating screw of fig. 1. The sleeve 11 includes a shaft portion 111, a limiting protrusion 112, and an assembly ring portion 113. The barrel 111 has an inner wall 1111. The inner wall 1111 surrounds a receiving space S. The limit projection 112 is, for example, annular. The limit protrusion 112 protrudes from the inner wall 1111 and forms a channel W. The passage W is, for example, a screw hole. The diameter R1 of the channel W is smaller than the diameter R2 of the accommodation space S. The assembly ring 113 is connected to one side of the barrel 111 and is assembled to a plate (not shown). The assembly ring 113 has an inner surface 1131. The inner surface 1131 surrounds an opening O. The diameter R3 of the opening O is, for example, equal to the diameter R2 of the accommodation space S.
The screwing member 12 is, for example, a screw, and is used for locking another plate (not shown). The screw 12 includes a head 121, a neck 122 and a stud 123. Neck 122 connects head 121 with stud 123, and diameter R4 of neck 122 is smaller than diameter R5 of head 121 and diameter R1 of passageway W. The neck 122 passes through the channel W, and the head 121 and the stud 123 are located on opposite sides of the limit protrusion 112. The stud portion 123 includes a large diameter portion 1231 and a small diameter portion 1232. The large diameter section 1231 is connected to the neck 122. The narrow diameter section 1232 is connected to the large diameter section 1231, and the diameter R1 of the passage W is smaller than the large diameter R6 of the large diameter section 1231, and is equal to or larger than the large diameter R7 of the narrow diameter section 1232 and the small diameter R8 of the large diameter section 1231. In this way, the large diameter section 1231 of the screw 12 passes through the passage W in a screw-fit manner so that the screw 12 is coupled to the sleeve 11 without disengaging the screw 12 from the sleeve 11. The size of the channel W and the large diameter section 1231 of the stud 123 is, for example, M5, and the size of the small diameter section 1232 of the stud 123 is, for example, M4. By M5 is meant that the diameter of the channel W and the large diameter section 1231 of the stud 123 is about 5 mm. By M4 is meant that the diameter of the narrow diameter section 1232 of the stud 123 is about 4 mm.
In the present embodiment, the neck 122 and the limiting protrusion 112 maintain a first gap G1. The large diameter section 1231 maintains a second gap G2 with the inner wall surface 1111. The narrow diameter section 1232 maintains a third gap G3 with the inner surface 1131. The first gap G1, the second gap G2, and the third gap G3 are, for example, 0.5 mm or more. For example, the first gap G1 is 0.9 mm, the second gap G2 is 0.85 mm, and the third gap G3 is greater than 0.85 mm. The clearances G1 to G3 allow the screw 12 and the sleeve 11 to maintain elasticity in assembly, so that the screw 12 is kept in a floating state when not fastened to the plate body.
In this embodiment, the floating screw 10 may further comprise a reset member 13. The reset piece 13 is sleeved on the neck 122 of the screw piece 12, and two opposite sides of the reset piece 13 are respectively connected with the head 121 of the screw piece 12 and the limit convex part 112 of the sleeve 11 so as to force the head 121 to be relatively far away from the limit convex part 112, thereby being convenient for unlocking the screw piece 12 and the plate body.
In the present embodiment, the number of the limiting protrusions 112 is single, and the limiting protrusions 112 are annular, but not limited thereto. In other embodiments, the number of the limiting protrusions may be more than two, and the limiting protrusions are arranged in an annular shape.
Please refer to fig. 5 to fig. 7. Fig. 5 is a schematic cross-sectional view of the thick section of the screw in the floating screw of fig. 1 without passing through the limit projection of the barrel in the floating screw. Fig. 6 is a schematic cross-sectional view of a thick section of the screw in the floating screw of fig. 1 passing through a limit projection of a barrel in the floating screw. FIG. 7 is a schematic cross-sectional view of the floating screw lock of FIG. 1 secured to a plate.
In this embodiment, when a user wants to lock the two plates 20 and 30 by the floating screw 10, first, the user puts the screw 12 into the sleeve 11 disposed on the plate 20 along the direction a, and makes the thick section of the screw 12 pass through the channel W in a screwing manner, so that the screw 12 is combined with the sleeve 11. Finally, the user screws the screw 12 to the plate 30. Thus, the locking of the two plates 20,30 by the floating screw 10 is completed.
On the contrary, when the user wants to unlock the two plates 20 and 30, the user only needs to unlock the threaded member 12 from the plate 30, so as to unlock the two plates 20 and 30. Since the diameter R1 of the passage W of the sleeve 11 is smaller than the large diameter R7 of the large diameter section 1231 of the screw 12, that is, the large diameter section 1231 cannot pass through the passage W in the reverse direction of the direction a, the screw 12 is not separated from the sleeve 11.
In the present embodiment, the diameter R3 of the opening O surrounded by the inner surface 1131 is equal to the diameter R2 of the accommodating space S surrounded by the inner wall 1111, but not limited thereto. Please refer to fig. 8. Fig. 8 is a schematic cross-sectional view of a floating screw according to a second embodiment of the present utility model. In other embodiments, the diameter R3 of the opening O surrounded by the inner surface 1131 of the floating screw 10A may be smaller than the diameter R2 of the accommodating space S surrounded by the inner wall 1111.
Please refer to fig. 9. Fig. 9 is a schematic cross-sectional view of a floating screw according to a third embodiment of the present utility model. The floating screw 10B of the present embodiment is similar to the floating screw 10 of the first embodiment, so the differences between the present embodiment and the first embodiment will be described below, and the details of the differences will not be repeated. The floating screw 10B of the present embodiment may further comprise a glue layer 14. The adhesive layer 14 is disposed on the thick diameter section 1231 of the stud 123, and can absorb the vibration generated when the screw 12 is mounted on the sleeve 11, so as to prevent the screw 12 from being ejected out of the sleeve 11 when being mounted.
According to the floating screw of the above embodiment, since the thick section of the screw passes through the passage of the sleeve in a screwed manner and the diameter of the passage is smaller than the large diameter of the thick section in the floating screw, the screw cannot be separated from the sleeve from the passage. Thus, the structure of the floating screw can be simplified so as to be convenient for a user to assemble. In addition, the screw-on piece is not lost due to falling off from the sleeve.
Although the present utility model has been described with reference to the above embodiments, it should be understood that the utility model is not limited thereto, but rather, it should be apparent to one skilled in the art that modifications and variations can be made without departing from the spirit and scope of the present utility model.
